It looks like Americans were a bit more curious in June than in May as revealed by Podtrac’s monthly ranker of the most popular shows among publishers it tracks. It shows the iHeartPodcast Network show Stuff You Should Know jumped to second place last month as the New York Times-produced The Daily remained No.1 for the eighth consecutive month, based on U.S. unique monthly audience. This American Life/Serial slipped back one spot to third, with NPR’s Up First and The Daily Wire’s Ben Shapiro Show remaining in fourth and fifth place in June, just as they were in May.

There were bigger moves among the bottom half of the top ten. WNYC Studio’s RadioLab jumped from No. 9 to No. 6 month-to-month. And NPR’s Wait Wait…Don’t Tell Me advanced two spots into tenth place.

While most of the podcasts that appear on Podtrac’s top 20 are shows that publish daily or weekly, a few shows also prove that limited-run series can break through. Wondery’s The Shrink Next Door debuts at No. 15. Produced in partnership with Bloomberg, the podcast—hosted by journalist Joe Nocera—is timed to coincide with summer vacation season as it explores the world of a therapist to celebrities and Manhattan’s elite in their New York playground: the Hamptons.

And some shows prove popular even when they move out of production. That’s the case for iHeartPodcast Network’s The Ron Burgundy Podcast. It is on hiatus until August when a second season is scheduled to launch. One reason it likely popped back onto the Podtrac ranker was iHeart released a “bonus episode” last month that featured Burgundy’s interview with Alex Rodrigues, the former New York Yankee and current co-host of the Barstool Sports podcast The Corp.

Here’s the list of the top shows in June among publishers measured by Podtrac:

The numbers reflect an update made by Podtrac in April to the measurement algorithm that calculates unique downloads. It was brought about by Podtrac’s embrace of standards develop by the Interactive Advertising Bureau (IAB) Tech Lab. The IAB’s Podcast Measurement Technical Guidelines 2.0 change what counts as a download. For example, in the past, if someone were to listen to a podcast, press stop, then play again, that would count as two downloads. Now, it counts as one. Plus, someone needs to listen for a full 60 seconds before it counts as a download. Podtrac has said that most podcasters didn’t see a “substantial” change in their unique monthly audience numbers, however download numbers mostly declined because of the new guidelines.
